To all whom it may concern:

Be it known that LMIou'AsL J. owma citizen of the United State's, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Glass-Shaping Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates tothe construction of a'machine for shaping glass; and it consists in' the constructionof a machine which will collect or gather the desired quantity of glass; further, in shaping the gathered glass into the form of a blank which maybe blown and; distributing the glass'around a blow-opening in the shaping of said blank; further, in the blowing mechanism cooperating with the gathering and shaping device by'which the gathered blanl: may be blown to its linal form.

The operations of the machine as herein shown are entirely automatic, and the machine operates continuously to gather the glass, shape it into the desired blank, and blow it to form without the intervention of any labor whatever. While I believe that 'such automatic machine is .the most desirable form in which to express my invention, I do not think that I am limited to the use-of such an automatic machine no: to the. manufacture of such hollow ware as bottles in finished shape, as

herein shown.

In the drawings, Figure 1 is a sectional elevation of the machine. Fig. 2 is a pen-spec tive view of one of the operating mechanisms. carried by the machine. Fig. 3 isadiagrammatic plan view. Figs. 4, 5, 6, 7, 8, 9, ll), and 11 are diagrammatic views illustrating the successive steps in the operation of the blank forming and finishing molds of the machine. Fig. 12 is a vertical section illustrating the operating mechanism for the blank-mold sections. Fig. 13 is a plan view of the inner portion thereof. Fig. 14 is an enlarged sectional view of the suction-head and a portion of the blank-formingmold. Fig.1.; is adiagrammatic view illustrating the drive connections and, timing devices for the various mechanisms. Fig. 16 is a section of one of thereverse driving-gears. Fig. 17 is an elevationof my ims'um No. 162,888. on model.)

proved machine, showing the tank or glass pool. in section, some of the details being omitted for the sake otclearness. Fig. 18 is a-vertical central section through half'of the machine, partly in elevation, illustrating one of the blank-forming or parison molds in po trating particularly. the actuating means for the mold-sections. Fig. 21 is a vertical section through the upperv part of the parisonforming mold. Fig. 22 is a vertical section through the bracket on the arm shown in Fig. 19, illustrating the manner of arranging the spring-support for the mold-carryingarm. Figs. 23, 2-1, 25, 26, 27, and 28 are diagram sections illustrating the position of the mold parts and shears at different points in the opcration.

Gem-ml xfructmc.-1 is a' base, 2 is a col umn rising from this base, and 3 is a revoluble frame journaled upon said column. This frame carries the mechanism for completely forming the bottle or otherarticle to be. blown, which mechanism is designed to complete the cycle ofitls movements with each revolution of theframe. The mechanism includes means for gathering the glass and forming the blank or parison, which is accomplished while the frame 3 is stationary and the blankforming mold is in registration with the tank or open-top'pool of molten glass-4. The succeeding operations in forming the'article are accomplishedduring the interval in which this blank-forming mechanism is carried around by the frame, so that when a complete revolution is accomplished a bottle will have been formed and the gathering means will again be in condition for repeating its operation.

To increase the capacity of the machine, a plurality of duplicate mechanisms are arranged aroimd the frame 3 and are carried thereby to successively be registered with the tank 4. Thus the frame 3 must be alternately partially rotated and then permitted to re main stationary, this intermittent movement being imparted thereto by any suitable mcch-' 8, with which a segment 10 on the crank 6 is 1' adapted to engage. Thus in operation the rotation of the crank 6 will cause the wrist 7 to enter the radial slot 8 to rotate the wheel through a certain angle of movement and then disengage from the slot, at which point 5 in the movement the segmental flange 10 engages with the concave bearing 9 and locksthe frame until another wrist 7 engages with the succeeding radial slot. The crank 6 is constantly'driven by any suitable mechanism, such as the worm-wheel 11, which engages .witha worm 12 on like longitudinally-extend ing shaft 13, which haft is connected by intervening gearing with-a motor 14, mounted uponthe base.

la'r standard 15, which is supported upon a roller-bearing 16 and. has'secured to its upper end the head 17., 1

18 is a head arranged above the head 17 and 39 connected thereto by a series of vertical posts;

19, arranged around the-periphery of said Tim gut/er; u 1 and blmul'jfimm iwg /m-rum., Each-of the duplicate mechanisms carried by the frame 3 includes a gathering and blank forming means of the following construction:-

, 20 is a vertically-movable support, which is shown in' the form of a skeleton frame slidingly secured toa pair of vertical posts-19.

4 This frame projects outward from the, frame 3 and carries at its outer end the suction-head 21, the sectional blank-forming mold, and

other mechanism whiclrwill be hereinafter.

described. Acommonmechnnism is provided for glowering and raisingeach of; ithe frmnes. 20 as they are successively registered with the tank 4. This mechanism consists of a rod 22, 3 arranged, within the column 2 and having at its. upper end a head 23, projecting outward2 5 through the slot in said column and provided with a lateral slot or way 24. The lower end of, the rod 22 is connected with a level-25,which at its opposite end is connected by alink 26 with theactuating cam-wheel 27 said cam being so.-

cured to a shaft 28, journaled in bearings upon the base. .Thc'shaft 28 is drivenfromthe motor 14 through the medium of a shaft 29, lnu'inga gear connection with said motorand the shaft 13, together with a worm30 on saidshaft l3 and a wormrwheel 31 on the shaft 28, thearrangcment being such that-the rotation of the cam wheel 27' will periodically impart a ,vertical.

This fulcrum may be adjusted by an engagement with a screw 38, which has a worm-and-gear connection 39 with a hand I a wheel shaft 40, extending to the side of the 5 The frame 3 preferably comprises a tububase.

T/u' blahksfm'm-ing mold.As has been stated, the gathering and blank-forming mold iscarried at the outer end of the frame 20.

This mold isdivided horizontally and verti cally into separable sections, said sections together forming a'rnold-cavityof the shape of the .blank and open at its lower end. Each of thesectionsis carriedby 'a jaw pivoted to the frame 20andadapted ,to swing in a horizon tal plane. ,The upper moldsection's 41 and 42 together constitute. what I shall term the neck'-mold-. This term 'is used as merely indicating the portion of the blank which is formed by this mold-section in the operationof form'inga bottle.'. I do not, however, intend to be limited by this term to a construc tion whichis only adapted for the formation of'the neck'of a bottle, as it is obvious that the machine may be put toother uses. The

sections-A1 and 42 are respectively conncct-,., ed .to the jaws 43-and fulcrumed upon the veg; ticalipins45, depending-from theframe 20.

46 and 47 are the two lower mold-sections, constituting what I Shall term-the bodymold, and these sections areiparried bythe;

adapted to engage with corresponding inclined faces onthe lugs 50. The hooks 51,

are secured to rods 52, passing upward through bearings in the suction-head and secured at their upper ends to the cross-head 53, slidingly engaging vertical posts or guides 54 of the frame 20. A yielding connection between the rods 52 and the cross-head 53 is provided by sleeving the springs 55 on said rod, which and 61- is a 'worm meshing therewith and driven by a universal-jointed shaft 62, which will be hereinafter described.

With the construction just given the rotation of the crank 58 will cause the upward movement of the cross-head -53, which-will ,draw upward. upon the rods 52, thereby causing the hooks 51 to clampthe lugs 50. The

springs 55 will permit of sufiicient yielding between the rods and cross-head to prevent. danger of breakage of parts and at the same time to maintain suflicient tension to firmly lock the mold-sections together. In addition to the clamping of the mold-sections 46 and 47 to each other these sections are also firmly clamped against the neck-mold sections 41 and 42, andthe latter in turn are clamped against the lower face of the suction-head 21.

The suction-head 21- has formed centrally therethrough the aperture 63, which is in axial alinement with the' cavity of the blank forming mold. Surrounding the central aperture is an annularchamber 64, which is se'paratedfrom aperture 63 by the wall 65.

The latter preferably extends downward be yoiid the lower face of the suction-head and engages with the corresponding recess in the neck-mold sections 41 and 42. 66 is a plunger adapted to pass through the aperture 63 and having formedat its lower end the core 67. The function of this core is to form a blowingcavity in the upper end of the blank and also to shape a portion of theinteriorofthe neck of the bottle. The plunger 66 is of slightly lesser diameter than the aperture 63, so that when in position there will be a slight space for the passage'of. the air from the mold-cavity around the plunger. This space is. however,

so slight-as not to permit the 'drawing of I glass into the passage. I

68 is the block upon the plunger, which when the latter is'in position rests upon the upper face of the suction hcad 21. 69 is a passage formed within the plunger and leading from an annular groove 70, which'is just above the core 67. This passage extends into the block, 68 and communicates with a port which is in registration with the port 71 in the-suction-head connecting with the vacuum-chamber 64. Thus whenever the plunger is in position the vacuum-chamber 64 is in direct communication with the annular groove 70, which latter communicates through the narrow slit surrounding the plunger with the mold-cavity. The annular recess 64 within the suction-head communicates with the corresponding annular recess 72, formed in the neck-mold sections, and this recess in turn communicates "with channel 73, formed in the adjacent faces of the body-mold sections 46 and 47. These channels are for the purpose of preventing the possibility of leakage of air into the moldcavity between the adjacent faces of the moldsections. All such leakage will first pass into the vertical channel 73 and annular channel 72, which are always in communication with the vacuum-chamber.

With the mold constructed as thus far de- 4 scribed it is evident that when the supporting-framc therefor, 20, is lowered the lower face of the body-mold sections 46 and 47 will be dipped into the molten glass-in the tank 4, as shown in Fig. 5. If then the suction is applied tothe vacuum-chamber 64, the pressure will be red need in the mold-cavity, which will cause the external atmospheric pressure to force or move the glass upward through the open end of thecavity until the latter is completely filled. The air is exhausted from the cavity not only through the crevice surrounding the plunger 66, but also preferably through a slight crevice 73" between the neck and body forming molds and intermediate the annular chamber ('4 and the mold cavity. These crevices are, sufiicient to rapidly exhaust the air from the cavity, but will not permit the molten glass to enter therein on'account of the chilling effect of the-metal.

(,'ut-n f/'.---After the mold-cavity is filled with glass and the moldsare again raised by the upward movement of the frame 20 it is necessary to cut oif the adhering connection with the glass from the tank. This is preferably accomplished .by blade 74, which is moved across the lower face of the body-mold sections, first cutting off the glass and then forming a bottom for the blank-mold. The blade 74 is secured to a lever 7 5, which is fulcrumed at the end of a rock-arm 76. the latter being connected to a rock-shaft 'l'l', journaled in hearings in the frame 20. A rod 78 connects the opposite end of the lever 75 with a bracket 79 on the arm 76, and a spring 80 is sleeved upon the rod to form a yielding buffer, which permits the blade 74 to travel across the bottom of the mold in contact there with. The rock-shaft 77 is actuated through the medium of a. worm-segment-Bl, engaging with a worm 82 on universally-jointed shaft 83, extending to the controlling mechanism, to be hereinafter described. Before the blank thus formed can be blown the core 67 must be withdrawn. This is accomplished by the raising of the plunger 66 through the following mechanism: 84 is a second cross-head slidingly secured to the vertical posts or guides 54, and this cross-head is connected to the shank of the plunger 66.

85 is a lever engaging a slotted bearing 86 in the cross-head 84 and pivotedupon-a shaft 87 at the rear of frame 20. Adjacent to this lever ,85 andpivoted. upon the same shaft is the lever 88, which at its forward end has a slotted bearing 89 embracing the lever 85.- The opposite end of the lever 88 hasformed thereon a wormsegment 90, which meshes with a worm 91 upon'a vertical shaft 92. Thus the rotation of the worm in onedirection will cause a movement of the segment 90 and through the lever 88 this movement will be imparted to the lever 85 and from the latter to the cross-head 84, which will raise the plunger 66 and withdraw the'core 67 from the mold-cavity and the suction-head.

After the core is withdrawn it is necessary to close the aperture 63 in the suction-head before admitting the blowing-air thereto; For this purpose a cover-plate 93 is provided,

which is slidingly secured in guides 94 on the suction-head. This cover-plate is withdrawn from the ath of the plungerduring the movement of t m atter by a'link 95, which is actuated by a cam 96. The can: .96 is secured a vertically-sliding head 97, engagingwith a guide 98 and actuated by a screw 99 on the shaft 92. The end ofthe link 95'which engages with the cam 96 is supported by the swinging link 100, pivotally secured to the frame 20'; ,W'itlrthe arrangement just described during the upward movement of the cross-head 84 and plunger 66, due to the ac tuation of the worm'91, a movement will simultaneouslyimparted to the cam 96 through the medium of the screw 99 and head 97. The

movement of the cam will cause the link 95 to be pro ected forward, which will carry the cover 93 down the incline guides 94 until it bears against the hpper faces of the suction-' head and covers the aperture 63. A yielding section or a spring 101 is preferably placed in the link 95, so that theieo firmly pressed against the silti on -head' by the mechanis'nidescribed withou't'dati r of break- 7,

this conduit loeated a valve 103. 104'i's the valve-stem,' which passes out frolnth'eonduit and extends'into proximity 'a'lever 105, fulcrum'ed on "frame v20. The opposite arm of this lever extends into the'path of an arm 106, depending-from the lever 88 which ari'n 'pref erably carriesithe adjustable serfeii' '107 for contacting with the lever 105. 1 'As has already bee'n" described, the ,le'veifl 88 has the slotted bearing 89 embracing"the'iever 85. The slot in this' bearing length.

"ei? 93 may be" the movement of theeo'ver 93 within the column 2.

to permit a slight lost motion between the levers 88 and 85, which is, however, normally taken up by a spring 108. In the downward movement of the levers and 88 the former will be held against the lower end of the slotted. bearing bythe tension of the spring 108 until the block 68 of the plunger rests upon the suction-head. The lever 88 is, however, provided with a further movement, whichjs permitted by the slotted bearing-and the yielding of the spring 108. Dur ing this,furthermovementthe screw 107 con tacts with the lever 105 and actuat'es the same,

together with the stem 104 in thepath of said lever, so as to open the valve'103. This valve is therefore held open as longas the parts re main in this position. In the reverse movement which withdraws the plunger, the worm 91 and-segment will first actuate the lever 88 and withdraw the screw 10? from the lever before any motion is imparted to the lever 85. Thus the valve 103 is closed through the actuation of a spring 108 by the-withdrawal of the core. l I ,lu the subsequent operation of completing the bottle or other article formed the bodyblank-mold sections must be separated and a blowing-mold of the desired configuration placed around the-blank. During this operation the blank is suspended by reason of this engagement with the neck-mold, and for this purpose the latter is formed of such a shape as to interlock with the blank. As shown, this interlocking is prod need by grooving the interior of the neck-mold soas to form a' rib in the blank; but it is obvious that any other shape which would look the blank to the mold would answer the purpose'equallywell. The body-blankmiold sections are opened by the movement of the supporting jaws 48, These jaws are preferably actuated by rearwardly extending arms 49, which are connected to each other by toggle-levers 109. During the gathering operation these toggle-levers are in a position tdjs'pread the arms 49,:and therefore Tlie'seetions'are opened by ii. movement of tlie' toggle vhieh will "draw tli'e arms 49 ward each other, and thereby separate the jaws' 48"ahil'mold-sections '46 and 47.

The'finishing or blowing mold is preferably i formed of. two laterally-separable liody-sec- E- tions 116 and bottom section 117. These are carriedby aswinging arm or frame 118, wlnch l ispivotally connected to-the-h'cad 17. The

mold-sections 116 are carried by jaws 119. 'which are pivotally connected to the frame 118. The opposite ends of these jaws are connected to t0ggle-lever120, which in turn are I connected to the piston-rod. 121 of a pneu matic motor 122. The bottom section 117 is secured to an ,arm 123 of the frame 118 through i the tank, and thus when the moldsare finally actuation of the shaft 129, worm 128, and seg- -through the actuation of the pneumatic mo; tor 122 and the tog le 120.

The frame 118 may be swung from a downwardly-hanging.position into a substantially horizontal position through the ment 127, and in this latter position the moldsections 116 will be arranged upon opposite sides of the blank. The sections are closed ing of the blank w1t in the finishing-mold, as will be hereinafter described,- the neck molds are open to disengage the same from the neck of the bottle and to permit the latter to be withdrawn by the finishingmolds. These. neck-molds are operated by connections similar' to those used for actuating the body-blank molds, comprising the rcarwardly-projecting arms44 on the jaws 43 and the connecting-toggles 130. The neck-molds are, however, open fore are normally held closed by .the tension joint. The opening of the molds is caused by engagement of a roll ,132 on the togglemovements the body-blank mold must be again closed, which may be effected either by a stationary cam on-the c'olu'mn engaging on theopposite end ofthe rack-bar 111. This head is adapted to engage with the roll 114' when the molds are in their last stationary position before being again registered with turned into registration with said tank they are closed and in position for the dipping operation.

Drive crmncctiorw and timing.-All of the mechanism which has thus far-been described is preferably actuated by'the'motor 14 through eonnectin g mechanism constructed as follows:

135 is a shaft extending longitudinally of the base andrdriven from the motor l4nthrough a car-train 136, shaft 29, and gears 135'. 13 7 represents beveled gears connecting the shaft 135 with the shaft 138, which extends verof, and connected therewith by intermeshingbeveled pinions 146. Upon each of the shafts 145 are mounted four independent reverse drive connections, respectively, 147, 148, 149, and 150. These reverse drive connections are all similar in construction, and each comprises a pair of oppositely-facing beveled gearwheels151 and 152, loosely sleeved upon the shaft, and an intermediate beveled gear 153, intcr'meshing therewith and constituting the driven member. Between the beveled gear- .wheels 151 and 152 is arranged a couplingsleeve 154, which is feathered to the shaft and is capable of being moved longitudinally thereon into engagement with either one of the beveled gear-wheels151 and 152. Thus when the sleeve is in engagement with the beveled gear-wheel 151 the beveled gear 153 .will be driven in one direction, and when said sleeve is engaged with the opposite gear 152 the gear 153 will be driven in the opposite direction. Again, when the sleeve 154 is in its central position all of said beveled gear-wheels re-' .main stationary.

the vertical movement of the frame 20. They IIO are also provided with universal couplings 'desc'i ibed. is controlled by a cam, which cams are mounted upon shaft 157, journaled in bearings upon tlie'hcad 'l S-and (standing par- :rllrl to tl'icshaft 145. I This shaftalifl is driven .ithrough a worm gear-wheel 158, meshing with 4 aworrh 159 upon the shaft 142 I '{160ns a cam controlling the reverse drivegearing 147 through- 'the medium of a link 161 --;a-n"d1the' lever 162, the latterbeing connected to the1slee\-'.e'15-4.' 163 164 1 mm cams simi;

larlyiconn ected' to' a controlling reverse drive figearing 148,149, and 150; These cams are all properly timed to actuate. their, respective mechanisms, as will be hereinafter set forth.'

lt'has been already stated that the rack-bar 111, controlling the opening and closing-of the body-blahkmo'lds, isactu'ated through a pin- 7 ion 112' upon a shaft 113, extending longitudinally'within the column 2. a "This shaft113 is driven through beveled gear-wheels 166,

' connecting. it with the shaft 167, extending longitudinally of the 'ba'se.. Upon this shaft is'arrangeda reverse dri've-gearin'g'similar to those previously describedand comprising the. beveled gear-wheels.168, 169, and 170. The gears 168 and- 170 are sleeved upon the shaft and may be alternatively cou'pled therewith'through' the medium of the sleeve 171, controlled by a lever 172, which in turn is controlled by a cam 173 upon the shaft 28.

l The gears 168, 169, and 170 are constantly driven through a gear-train 174, deriving its motion' from the shaft 29. With the mecb'. anism ust described the shaft .167 may remain either stationary or be driven alternatjvely in opposite directions through the controlling of the cam 17 3, and this cam is so 'timed as to produce the required movement in the operation, as hereinafter set forth.

' The suction and blowing connections for the molds-are preferably constructed by arranging at the upper end of the extension 142 of the column 2 the, revoluble suctiowchamber 175 and the chamber 176 for the blowing air.

The chamber 175 has a plurality -'of flexible connections 179, which are-respectivelyscon- 'nected to the conduits 1020f the several suction-heads; The blowing-chamber 176 is connected by a conduit 180 with the head- 21.

Fo ontro'lling the air-passing through this conduit a valve 181 is. arranged therein, which actuated by'a cam 182 upon the shaft 157. This cam is timed to turn on and off the air from the head 21 at the propel-points in the operation to effect the blowing of theblank;

As has been described, the suction co municates in the head 21 with both the 'ann lar chamber 64 thereof and also with the centralaperture 63, so .as to draw the air, from the suctionmold both from the top'of the cavity and through the crevice between the inner portions of the neck and body-blank molds. For blowing the blank air must be admitted only to the central chamber .63, and 'to accomplish this the connection is preferably formed through a passage 183,. formed in thecoverplate 93-' This passage connects at one endsite end witha channel 184 .in-'tl icwhich channel is connected tothe condpit18i0. Air connections {also extend from the airchamber 176 to each of the pneumatic'motors .j 122 through the conduits 185. In each of i' these conduits is arranged acontrolling valv'e 1 186.', 'w-hich is'actuated by a cam 186. on" the I: shaft 157. 1,86 is a second valve'in the condint-185, arranged upon one of the'trunnions 126 of the frame 118 and automatically op erated bythe swinging of said frame'to alternatively connect with .co'nduits186 andj 186, leading to'opposite ends of the cylinder 'of the pneumatic inotor 122. the arrangement {I being such that whenthe frame 118 is turned upward,'so as to bring the finishing-molds in. connection with the neck-molds, air will be closing of the finishing-mold sections about the blank. On the other hand, wbe'nthe frame bottle in the finishing-mold, the valves 186 and 186 will be operated to cause an opposite movementof the piston in the pneumatic in'otor 122, which will open the sections of the areprov-ided with any suitable supply .con-

nections, such as the conduits 177 and 17 8, ex-

tending downwardly through the column.

Operation of the machine: The machine 189, running upon a.- suitable track. When arranged in operating position, motion is com- "mun icated to-the various parts of the mechanism from the motor 14, which is tinder the control of the operator. This motor is prefmay be regulated according to the requirements. In the initiaiposition of parts (shown frame 3 is directly above the tank 4. The

closed and locked by the clamping mechanism, described. The first operation is the lowering of: the. frame 20 to effect-the dipping of the body-blank molds below the surface of the molten glass within the tank. This, as has been described, is accomplished by the cam 27 actuating'the link 26, lever 25, rod 22,

- 118 -is swung downward,- carrying with it the constructed as-described may be moved in or 'out of operative relation to the tank 4 preferably by mounting the base 1 upon wheels erably provided with suitable speed-contr0l-' ling devices, by' which the speed of operation admitted tothe pneumatic motor to cause the finishing-mold' The chambers 175 and 176 in Fig. 4) the frame 20 upon the revoluble 'IIO blank-molds carried by this frame are also and head 23, causingv the latter to move up lowered position by a suitable formation of" lever 88 will take up the lost motion in slotted tion of a shaft 83 and through the worm 82 anism rocking the lever 88, so as to withdraw nu ld-cavity. A further movement of the le- Yei' 88 will effect the opening of the valve 103 through the medium of thearm 106, screw 107, lever 105, and stem 104. It will thus be understood that as soon as the mold is dipped into the molten glass, as shown'in Fig. 5, the core will he in position and the suction is is applied, thereby filling the mold in the manner previously described. During the filling of the mold the frame 20 is held in its the cam 27. After a brief interval this cam will cause the reverse movement of connected mechanism, which will raise the frame 20 to its original position; Immediately succeeding this operation the cam 163 upon the shaft 157 will cause the operation of the reverse drive-gearing 148, which will cause the rotaand'worm-segment 81 will rock the shaft 77, swinging the'arm 76 downward. As this arm carries the cut-off blade 74;, the latter will be moved across the lower end of the body-blank molds severing the string of molten glass which ha's been'drawn upwardwith the mold and forming a bottom for supporting the glass within the mold-cavity, as'shown in Fig. 6. The suction-valve, which has been maintained open during the movement of the cut-off, is next closed. This is efiectedby the cam 164 actuating the reverse drive-gearing 149 to cause a rotation of the shaft 92in the reverse direction and through the intermediate mechthe screw 107 from contact with the lever 105. The spring 108 will then cause the closing of the valve 103. The further movement of the hearing 89'and'cause the lifting of the lever 85, which in turn raises the cross-head 84 and plunger 66. Simultaneously the screw 99 will move downward the hearing 97 upon the guide 98, carrying the cam 96 and causing the latter to actuate the link 95, so as to move the cover 93 downward on the guides 94 until it contacts with the upper faces of the suctionhead and closes the aperture 63. This also registers the passage 183 in said cover with the channel 184 in the head 21, so as to complete the connection for the blowing air. Dur-- ing the operations thus far described the revoluble frame 3 remains stationary and is locked in this position by reason of the engagement of the segmental liange lUon'the crank 6 with actuating the toggle connection 109. arms 49 are thus drawn toward each other,

the concave bearing 9 onthe starwl'ieid 5. As soon as this segmental hearing passes out 5 of engagement the roller-wrist will engage l with one of the radial slots 8 and will impart a rotary movement of the star-wlu-el and the frame Cl, which movement will bring another frame 20 inlo registration with'thr tank, after which llumechanism carried by said framiwill repeat the opcralions which have been alescrilu-d. The period of limeduring which the glass is inclosed by the body-blank molds "the body-blank molds are opened by the cam 173 actuating the lever 172 and coupling sleeve 171, so as to drive the shaft 167, beveled gear-wheels 166,-and shaft 113. --The pinion 1-12 on this latter shaft will then move the rack-bar 111 inward, causing the-engagement of the hook 110 with the roll 114 and The and consequently the jaws 48 are swung outward, thereby separating the mold-sections 46 and 47, as shown in Fig. 8. The separation of the n1old-sections is permitted for the reason that said sections have already been unclamped through the operation .of the cam 160, reverse drive-gearing 147, shaft 62, worm 61. worm-gear 60, rock-shaft 57, and crank 58. The movement imparted to thislcrank lowers the cross-head 53 through the link 59, thereby carrying downward the rods 52 and clamping-hooks 51, so as to disengage the latter from the lugs 50. Simuitaneously with or immediately succeeding the opening of the body-blank molds the cam 165 will actuate the reverse drive-gearing 150 to impart a rotation to the shaft 129, and through the worm 128 and worm-gear 127 will rock the frame 118, carrying upward the finishing-molds supported thereby. During the upward movement'of the frame 118 the mold-sections 116 are in their opened positions and will thus pass upon opposite sides of the blank, which is suspended from the neck-mold. As soon, however, as the frame has complcted its upward movement the valve 186 will be operated to cause a movement of the pneumatic motor 1.22, which will close the jaws 119, carrying the mold-sections 116. (Shown in Fig. 8.) The blowing air is next admitted to the head 21 by the operation of the cam l82," which opens the valve 181 in the conduit 180. This will cause the expansion of the blank until it fills out the cavity within the linishing-mo-hls. 'hen in the rotation of the frame 3 the-roll 132 for the toggle-levers lBUactuatihg the neck-mold sections comes in contact with the cam 133 on the'column, the said levers will be moved against the tension of the spring lI-ll into a position where the arms 44 are drawn toward each other and the jaws -13 are rocked outward. This will cause theopcning ol'tluneck-mold srrtionsil and-12 sulliciently to disengage the same from the neck of the bottle. (Shown in Fig. .l.) 'hihthe neckmold is open the frame ll8 will be rocked downward again, thereby carrying the linishing' mold with the blown bottle therein.

" (shim-ii in Fig. 10.) Following this moi-'5;

ment the body-blank molds'iand neck-mold. sections are again closed, the former by theactuationof the head 134, which engages with the roll 114, and the latter by the spring 131' 1o ters the blank-forming molds with 'the tank.'

-At the conclusion of the downward movement of said frame 118 the valve 186 is operated to reverse the pneumatic motor, 122, thereby opening thesections 116 of the finishing-mold, r 5 was to permit the completed bottle to drop out, as shown in Fig. 11. During the final rnogement of the frame 3 the cam 160 actu- 'at'es the reverse drive-gearing 147 to again cause: the clamping of the sections'of the blank mold before anothenoperation ofj dipping." p

Itisto be understood that each of the separate groups of mechanism 'carri by the frame 3 operates in precisely the same way a 5 and the cycle of movements of each mechanism is comp eted in one revolution ofthe frame3. so'that in one revolution of the frame 3 the number of bottles completed is equal to the number of duplicate mechanisms.

In the modified form of machine shown in Figs. 17 to 28, A represents a suitable base. B is a standard extending upwardly and over the base. C is a' vertical shaft journaled 'on the base and supported by the inner end of the arm-B ef the standard. This shaft may be driven in any suitablemanner. 1 have shown it provided with a gearC, meshing with a suitable gear upon thedriven shaft 1.),

This tube or pipe Lserves not only as an air passage, as will be hereinafter described, butalso to steady the head H and-to insure the vertical movement of the mold G. The slide J extends upward above the post J andis preferably provided with a roller-bearing e. engaginga camf on the nn der side ofthe arm L, which extends out from the overhanging" portion of the standard B, as plainly shown in Figs. l'laud 18.

Whenever the pres sure is relieved from the slide, the spring K will act to lift it again to its upper position, as will be easily understood from the description already given.

The arm M is raised and lowered by its engagement with the camt'rack P and its incline S on the base A, this cam-track being of suitable shape to give the raising and lowering movements tothe moldsection M, hereinafter described. I have shown a series of arms F extending radially from the sleeve E and in connection with each one a parison-mold 1i and a lower mold-section M and actuating devices for these parts; i

In the shaft 0. I have shown two passages m and 14. At the lower end these passages connect into the annular chambers o and 0', respectively. these chambers being formed in the sleeve E on the base A with suitable packing to maintain a tight joint.
